The Milwaukee M18 FUEL 2904-20 delivers the highest torque in its class at 1,200 in-lbs, making it ideal for drilling into concrete and steel. Owner reviews consistently praise its reliability on job sites, with many noting it handles continuous heavy use without overheating.
The tool-only weight of 4.2 lbs is heavier than some rivals, but the power-to-weight ratio is industry-leading. The M18 battery platform offers a wide range of compatible tools, which is a major plus for professionals already invested in Milwaukee.
DeWalt DCD805
Best Balance & RuntimePros

The DeWalt DCD805 is a favorite among professionals for its balanced design and extended runtime. It produces 820 in-lbs of torque, which is sufficient for most drilling and screwdriving tasks, and its brushless motor maximizes battery efficiency.
Owner reviews highlight its comfortable grip and low vibration, reducing fatigue during long workdays. While it lacks the raw power of the Milwaukee, it is lighter and more maneuverable, making it a top choice for overhead work and tight spaces.
Makita DHP484
Best Budget ProPros
- Affordable for pros

The Makita DHP484 is a solid entry-level professional combi drill that offers good value without sacrificing reliability. With 480 in-lbs of torque, it handles wood and metal drilling well, though it struggles with heavy masonry compared to higher-end models.
Owner reviews commend its compact size and lightweight design, making it easy to use in confined spaces. While it lacks a brushless motor, its brushed motor is durable and easy to maintain, and the 18V LXT battery system is shared with many Makita tools.
Bosch GSR 18V-90 C
Best Compact PowerPros
- Very compact design
- High torque for size
- Smart connectivity features
Cons
- Battery not compatible with older Bosch tools
- Higher price for compact model
The Bosch GSR 18V-90 C packs 900 in-lbs of torque into a compact 3.4 lb frame, making it one of the most powerful small drills available. Its brushless motor and smart connectivity allow for custom settings via a mobile app, which some professionals find useful for repetitive tasks.
Owner reviews appreciate its balance and power in tight spaces, but note that the newer battery system may not work with older Bosch tools. It is a strong choice for professionals who prioritize portability without sacrificing performance.
Ryobi P251
Best Value for MoneyPros
- Very affordable
- Brushless motor
- Wide battery compatibility
Cons
- Less durable for heavy daily use
- Higher vibration than premium brands
The Ryobi P251 offers professional-level features like a brushless motor and 750 in-lbs of torque at a fraction of the cost of premium brands. It is a great option for tradespeople who need a reliable drill without the high investment.
Owner reviews note that while it performs well for most tasks, it may not withstand the same level of abuse as Milwaukee or DeWalt models. The 18V ONE+ battery system is one of the largest ecosystems, making it a smart choice for those already using Ryobi tools.
What to check before buying a professional combi drill
Torque is the most critical spec for professionals. Higher torque allows drilling through masonry and steel with ease. Look for at least 800 in-lbs for heavy-duty work. Battery voltage and amp-hour ratings also matter; 18V or 20V systems with 5.0Ah or higher batteries provide longer runtime.
Chuck quality is another key factor. Metal chucks are more durable than plastic ones and reduce bit slippage. Weight and ergonomics affect fatigue during long use, so consider a model with a comfortable grip and good balance. Finally, check the brand's battery ecosystem to ensure compatibility with other tools you own.
Mistakes to avoid when choosing a combi drill
One common mistake is buying based on price alone. A cheap drill may lack the power or durability for daily professional use, leading to frequent replacements. Another error is ignoring battery compatibility. Investing in a new platform means buying additional batteries and chargers, which can be costly.
Some professionals also overlook the importance of a hammer function. If you drill into concrete regularly, a combi drill with a quality hammer mechanism is essential. Finally, avoid models with plastic chucks, as they wear out faster and reduce drilling accuracy.
